This video tutorial teaches how to compare fractions with different denominators by plotting them on number lines. It explains the concepts of numerators and denominators, and demonstrates how to use number lines to visually compare fractions. The tutorial includes examples comparing fractions like 2/3 and 3/8, as well as 1/8 and 1/3, highlighting how to determine which fraction is greater or smaller.

What does the numerator in a fraction represent?

• The value of the fraction on a number line

• The number of equal parts a whole is divided into

• The number of shaded parts in a whole

• The total number of parts in a whole

How can you compare fractions with different denominators?
